Metrics
Metrics grouped by scope.
The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
Per Socket statistics instance
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| ip.sockstat_sockets | used | sockets |
| ipv4.sockstat_tcp_sockets | alloc, orphan, inuse, timewait | sockets |
| ipv4.sockstat_tcp_mem | mem | KiB |
| ipv4.sockstat_udp_sockets | inuse | sockets |
| ipv4.sockstat_udp_mem | mem | sockets |
| ipv4.sockstat_udplite_sockets | inuse | sockets |
| ipv4.sockstat_raw_sockets | inuse | sockets |
| ipv4.sockstat_frag_sockets | inuse | fragments |
| ipv4.sockstat_frag_mem | mem | KiB |
Alerts
The following alerts are available:
| Alert name | On metric | Description |
|---|---|---|
| tcp_orphans | ipv4.sockstat_tcp_sockets | orphan IPv4 TCP sockets utilization |
| tcp_memory | ipv4.sockstat_tcp_mem | TCP memory utilization |
